ADJUSTABLE BENCH-HOOK.

filPl-JCIFICATION forming part of Letters Patent No. 302,385, dated July22, 1884:.

Application filed December .27, 1883. (N model.)

To all, whom it may concern.-

Be it known that I, HARRY Coornn, of San Antonio, in the county of Bexarand State of Texas, have invented a new and Improved AdjustableBench-Hook, of which the following is a full, clear, and exactdescription.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is aplan view of my improvement. Fig. 2 is a side elevation ofthe same. Fig. 3 is a sectional elevation of the same, taken through theline we", Fig. 2. Fig. 4 is a sectional plan view of apart of the same,taken through the line y y, Fig. 2.

The object of this invention is to facilitate the adjustment ofbench-hooks and promote security in holding the work.

The invention consists in a bench-hook constructed with a plate carryinga sliding bar, to which is adjustably secured a hook. The sliding barand hook are locked in place by a clamp and cam attached to the plate,and the plate and its attachments are locked to the bench-front by astationary lug attachedto the plate, and a movable lug attached toalever pivoted to the said plate and locked in place by a cam, so thatthe said hook can be readily adjusted upward,

0 3 work to be held may require, as will be hereinafter fully described.

A represents an ordinary work-bench,which is provided with a stationaryhook, B, in the 5 ordinary manner for the forward end of the is held bythe hook O, the shank of which extends downward at the forward side ofthe bench A, and has two vertical slots, 0, formed in its lower endtoreceive the,screws C by which the said hook issecured to the bar D, sothat by loosening the said screws G the hook G can be raised and loweredas the work to be held may require. The bar D is made with dovetailededges, and slides in a dovetailed groove in the upper part of the plateE, and is locked in place by a clamp, F, which is placed upon the screwG,and pin H, attached to the plate E, and which pass through holes inthe middle and lower parts of the said clamp F. The fordownward,forward, and backward, as the work to rest against. The rear end of thework' ward side of the iniddlepart of the clamp F is rounded or beveledlongitudinally to fit into the correspondingly-concaved inner side ofthe lever I, which is placed upon the screw G, and is secured in placeby a nut, G, screwed upon the said screw, so that the said lever willact as a cam to lock and release the clamp F. By this construction, byturning the cam-lever I to theright or left,the clamp F willbe forcedagainst the bar Band will lock the said bar and the hook O securely inplace, and by turning the said cam I into a vertical position the bar Dand hook G will be released, and can be readily adjusted as the work tobe held may require. The plate E is provided with twoinwardly-projecting pins or lugs,-J K, to pass through holes L in thefront of the bench A, and support the said plate E and its attach ments.The pin or lug J is stationary, and is attached to the plate E. The pinor lug K is .70 movable, passes through an inclined or curved slot, M,in the plate E. and is attached to the end of the lever N, which ispivoted to the plate E by a rivet, O, or other suitable means. Theforward part of the lever N is bent upward, so that its lower part willbe so low down upon the plate E as to be out of the way. With thisconstruction, by moving the rear part of the lever Ndownward, the lug Kwill be forced toward the lug J, so that the said lugs will be forcedagainst the sides of the holes L, and will clamp the plate E firmly tothe front of the bench A, and by moving the rear end of the lever Nupward the lug K will be forced from the lug J and the plate E will bereleased. 8 5 Holes L are formed in the front of the bench to receivethe lugs J K, so that the plateE and its attachments can be move towardor from the forward endof the bench A, as the length of the work to beheld may require. The rear 0 end of the lever N passes beneath the lowerend of the clamp F, so that the said clamp may serve as a guard to keepthe said leverin place against the plate E. The pins or lugs J K shouldbe roughened to prevent them from 9 5 slipping out of the holes Lwhenclamping the plate E against the front of the bench A.

To the rear end of the plate E is pivoted the cam P in such a positionas to bear against the upper side of the rear end of the lever N andlock thesaid lever in place when clamping the plate E to the front ofthe bench A.

In using the improvement, the hook Ois adjusted at the proper height tohold the work, and the 0am I is turned into a vertical position torelease the bar D. The bar D is then ad justed into such a position asthe length of the work to be held may require, the hook O is drawn intothe work, and the cam I is adj ust ed to lock the bar D and hook O inplace.

Having thus described niyinvention, I claim as new and desire to secureby Letters Patent 1. The improved bench-hook consisting of theattaching-plate E, provided with the horizontal sliding bar D, mountedin suitable ways in the upper face of said plate, and the verticalhooked bar 0, secured adjustably to said bar D by slots and set-screws OO, and a suitable clamping device on plate E, for holding the bar D inany desired position, substantially as set forth.

2. The combination, with the bench pro vided with holes L, of theattaching-plate E, carrying the bench-hook, and provided on its rearface, near one end,with pin .I, and on its front face, near its oppositeend,with a pivoted lever, N, carrying a pin, K, extending through aninclined slot, M, substantially as set forth.

3. The combination of the attaching-plate E, carrying a bench-hook, andprovided on its rear face with a pin, J, with thelever N, pivoted to thesaid plate, and provided with a pin, K, at its forward end, extendingthrough an inclined slot, M, and a clamping-lever, I, pivoted to theattaching-plate at the rear end of said lever, for clamping said leverin place.

mounted on stud G on the attaching-plate, and a cam-lever, I, also onsaid stud, and adapted to force the clamp against the horizontal bar I)for looking it in place,substantially as set forth.

5. The horizontal bar D, mounted to slide in 5 upper endon said bar D,fLIlClIDOLlDlJGd on a stud, G, on the plate F, said stud also carrying acam-lever, I, bearing on said clamp I for binding the clamp against thebar andlock ing said bar in place, substantially as set forth.

6. An adjustable bench-hook consisting of an attaching-plate providednear its top with a horizontal bar, D, sliding in suitable ways therein,said bar carrying a vertically-adj ustable hook-bar, C, a clamp, F, onthe screw G of the attaching-plate, bearing on the barD, a

cam-lever, I, also on said screw, for operating clamp F, a pin, J, onthe rear face of the attaching-plate near one end, and a pivoted le ver,N, carrying a pin, K,working through an inclined slot, M, and aclamp-lever for locking the rear end ofsaidlever, substantially as setforth.
